[Effect of formate on 14C incorporation from various precursors into rat liver proteins and lipids].
Experiments on the rat liver homogenates and slices show that formate stimulates carbon incorporation from [1-14C] lysine and [2-14C] acetate into proteins and from [2-14C] acetate into lipids. The stimulating effect depends on both the formate concentration and nature of the labelled precursor. The in vitro experiments demonstrate the highest stimulating effect on the metabolism of both proteins and lipids under administration of 2 microM formate per 100 g of animal mass. Determination of the label incorporation rate at different time after formate administration showed that the latter evokes an intensified synthesis of protein with rate of its decay remaining the same.
